Be 'it known that I, GEORGE PICKERING, a Icitizen. ofthe United States, residing .at

Dover, in the county of Kent and State of Delaware, have invented certain new and useful Improvements in Wheels, of Vwhich the following is a specification.

This invention relates to the class of l wheels with resilient tires, known as spring wheels, and intended to take the place. of wheels w`ith pneumatic tires in automobiles and other wheeled vehicles.

The' object'of the invention is to provide a wheel that is both resilient and durable, and not exposed in use to the frequent accidents that occur to pneumatic tires, and in which, in operation, the springs are relieved of excess ofstrain from overloading or from inequalities in the roadway.

y:[11 the drawings, which accompany this specification and are made a part. thereof,

'Figure l is a side elevation of the improved wheel with the upper portion in section; A

Fig. 2 is a front elevation thereof with the upper portion in section; and,

, ig. 3 is a perspective view of a section of the tire preferably used on the improved wheel.

Like numerals of reference apply to similar parts in all the views shown.

' The improved wheel consists of the elements whichfollow, in form and inter-relation 'as' hereinafter described; a hub l, spokes 2, an inner felly 3, an outer felly 4 separated a rim 5 and a tire 6. Radi-ally disposed between the inner felly 3 and the outer felly 4 and opposite the spokes 2 yare coil springs 7 bearing at their ends upon the fellies and held in tension by them. Fixedly secured on the inner felly 3 are annular plates 8, which extend outwardly from the felly' 3 in the direction of the other felly 4. Secured to the sides of the outer felly 4 adjacent its inner face I provide the annular plates 9. These plates are provided with inwardly odset flanges forming annularshoulders which are designed to abut the inner face of the feily and relieve the fastenings of any strain and alsonto position the portions of the plates which extend toward the hub inwardly and between the plates 8 hereinbefore referred to. It will thus be seen that the plates 8 overlie the plates 9 as clearly shown in the drawings.

The .riml 5, fQl-'nedi with: clencher flanges l2, is mounted t'onthe@fowiliter on flange 10.

felly 4 and clenches and carries the tire 6. The'tire 6 is made solid, ofany approved elastic material, is grooved longitudinally in the center of the tread and is furnished in the tread with transverse webs 14 formed thereon, the contour of the webs 14 making an angle, the apex of which extends beyond the extreme periphery of the tire 6.

It will be seen that the plates 8 and 9 are adapted to move radially upon each other in opposite directions, the movement being limited by the recurved flanges l0 and 1l.

When the springs 7 in the lower portion of the wheel are compressed by excessive load or by a shock, the inwardlyrecurved ange l0 on the plate 8 will interlock with the outwardly recurved flange l1 on the plate 9 at the upper portion of said wheel, arrest the downward movement of that portion of the wheel comprised within the periphery of the inner felly 3, and prevent any additional compression of the springs 7, thereby accomplishing a desirable result, as when the hub of a wheel, as in the case o f many spring wheels is forced by compression of the lower springs very considerably below the center, resistance to traction is increased. The angular contour of the faces of the transverse webs tends to prevent or minimize skidding, and gives the tire a better grip for purposes of traction.

In operation, when a vehicle equipped with the improved wheel is under traction,

shocks or jars from irregularities of surface t i 7' I l plates 8 are formed Aart- .their.. outencdges,

relieve the springs 7 of any excessive pressure, the weight being borne by the plates 8 and 9 and the supports of the plate 8.

Having thus fully described my invention, what I claim as new and desire to secure by United States Letters Patent, is

A wheel comprising a hub, spokes radiating from said hub, a telly at the outer ends of said spokes7 blocks supported onthe telly` arcuate pla/tes attached to the side edges of the felly and extending outwardly therefrom, inturned flanges at the outer edges of the plates, springs supported on the blocks,

a. rim supported on the outer ends of the Y springs, arcuate plates attachedr to the rim and extending inwardly therefrom, inturneel flanges on the extreme inner ends of the plates forming 'shoulders engaging the inner side of the rim, right singularly extending fflanges formed at the extreme inner ends of the last mentioned flanges and projecting inwardly to a point intermediate the flanges on the first, mentioned plates and the telly, the said flanges on the first mentioned plates rietionally `engaging the right angularly extending portion to torni dust tight joints between the plates on the telly and rim,

and outturned flanges on the right Iangularly extending vportion for, engaging the inners'ides ot' the inturn'edflanges on-the telly to limit the outward movement ofthe rim with' relation'to the telly.I In testimony7 whereof I allix my signature.
